Referring to fig. 1 to 8, a condensing device 10 according to an embodiment of the present disclosure includes a condensing tube 11 and a flow guiding assembly 12.
Referring to fig. 2 to 5, the condenser tube 11 has a water inlet 11c, a water outlet 11d, an air inlet 11a and an air outlet 11b, and a condensate flow path extending vertically downward is formed between the water inlet 11c and the water outlet 11d, that is, the water inlet 11c of the condenser tube 11 is located at an upper side of the water outlet 11d, and the condensate flow path formed between the water inlet 11c and the water outlet 11d extends from top to bottom, or condensate flowing into the condenser tube 11 from the water inlet 11c may flow along the condensate flow path from top to bottom under the action of its own gravity and flow out from the water outlet 11 d. An airflow flow path extending in the transverse direction is formed between the air inlet 11a and the air outlet 11b, that is, the air inlet 11a and the air outlet 11b are respectively located at two opposite sides of the condenser tube 11 in the transverse direction, and an airflow flowing into the condenser tube 11 from the air inlet 11a can flow in the transverse direction along the airflow flow path and flow out from the air outlet 11 b. It should be noted that the airflow flow path described herein only needs to extend in the lateral direction, and is not limited to flow from one designated side to the other designated side. The condensate flow path intersects the gas flow path, i.e. the gas flow path is required to pass through the condensate flow path, i.e. the gas flow passes through the condensate during its flow along the gas flow path.
The specific composition of the condensate is not limited, and may be water or other types of liquids.

It should be noted that the low-temperature drying air flow is relative to the wet hot air flow, and the temperature of the low-temperature drying air flow is lower than that of the wet hot air flow. The low temperature in the embodiment of the present application may be room temperature.
The condensing unit 10 of the embodiment of the present application may be used in any suitable application. Exemplarily, the embodiment of the present application is described by taking the condensing device 10 as an example of being applied to a laundry treatment apparatus.
Referring to fig. 1, an embodiment of the present application provides a clothes treating apparatus including a drum assembly 20, a filtering device 30, an air guiding device 40, and a condensing device 10 according to any embodiment of the present application. The drum assembly 20 is provided with a laundry treatment chamber, and an air inlet and an air outlet communicated with the laundry treatment chamber; the filter device 30 is communicated with the air outlet and the air inlet 11 a; the air guide device 40 communicates the air outlet 11b and the air inlet. In the air guide device 40, a fan and a heater are disposed.
Specifically, the airflow channel 11e of the condensation device 10 shown in fig. 1 is arranged along the left-right direction of the cylinder assembly 20, that is, most of the area of the airflow channel 11e extends along the left-right direction of the cylinder assembly 20, and in some embodiments, the airflow channel 11e of the condensation device 10 may also be arranged along the axial direction of the cylinder assembly 20.
The drain port 11d of the condensation device 10 shown in fig. 1 is located at the rear side of the cylinder assembly 20 in the axial direction, that is, part of the structure of the condensation device 10 may extend to the rear side of the cylinder assembly 20 in the axial direction to facilitate drainage.
An air flow circulation channel is formed in the clothes treatment equipment, the air guide device 40 guides dry hot air to the clothes treatment cavity through the air inlet, in the clothes treatment cavity, the dry hot air flows through the surface of wet clothes to exchange heat and moisture with the wet clothes to absorb moisture in the clothes and change the dry hot air into wet hot air, thread scraps, impurities and the like generated by the clothes are mixed into the wet hot air in the clothes drying process, the wet hot air flows wrap the thread scraps and the impurities sequentially flow out through the air outlet and then enter the filtering device 30 to be filtered, most of the thread scraps and the impurities can be removed by the filtered wet hot air, however, a small amount of small-size hair scraps can enter the condensing device 10 from the air inlet 11a along with the wet hot air, condensate in the condensing device 10 is condensed and dehumidified to form low-temperature dry air flow, and the low-temperature dry air flow enters the air guide device 40 from the air outlet 11b, the air is heated by a heater in the air guide device 40 to form a drying hot air flow. The drying hot air flow enters the clothes treatment cavity again, the flocks wrapped in the wet hot air flow are mixed into the condensate along with the condensed water and are discharged through the water outlet 11d, and the circulation operation is carried out, so that the continuous and efficient drying of the clothes and the filtering and the flock removal are realized.
Referring to fig. 3 to 5, the flow guiding assembly 12 is disposed at an intersection of the condensate flow path and the air flow path, the flow guiding assembly 12 includes a flow collecting plate 121 having a flow collecting groove 121a, the flow guiding assembly 12 in fig. 5 is provided with a plurality of flow collecting plates 121, the plurality of flow collecting plates 121 are spaced apart in the condenser tube 11, and in some embodiments, only one flow collecting plate 121 may be provided. The collecting groove 121a serves to collect the condensate flowing along the condensate flow path and to guide the condensate to overflow from at least one of opposite sides of the collecting groove 121a in the gas flow direction. It should be noted that the airflow direction refers to a direction in which the airflow flows along the airflow path.
Specifically, the condensate flows through the current collecting plate 121 during flowing from top to bottom along the condensate flow path, referring to fig. 5, the condensate flowing through the current collecting plate 121 first flows into the current collecting groove 121a, and when the condensate in the current collecting groove 121a is excessive, the excessive condensate overflows from the current collecting groove 121a, in the flow guiding assembly 12 shown in fig. 5, the current collecting grooves 121a on each current collecting plate 121 are configured to guide the condensate to overflow from two opposite sides of the current collecting groove 121a along the airflow flowing direction, in some embodiments, the current collecting grooves 121a on each current collecting plate 121 may be configured to guide the condensate to overflow from one of the two opposite sides of the current collecting groove 121a along the airflow flowing direction, or the current collecting grooves 121a on one current collecting plate 121 may guide the condensate to overflow from the two opposite sides of the current collecting groove 121a along the airflow flowing direction, and the current collecting grooves 121a on the other current collecting plate 121 may guide the condensate to overflow from the two opposite sides of the current collecting groove 121a along the airflow flowing direction One of the sides overflows. When the flow guide assembly 12 has only one flow collecting plate 121, the flow collecting plate 121 may be configured to guide the condensate to overflow from two opposite sides of the flow collecting groove 121a in the flowing direction of the air flow, or may be configured to guide the condensate to overflow from one of two opposite sides of the flow collecting groove 121a in the flowing direction of the air flow.
The condensing groove 121a can slow down the flow velocity of the condensate by gathering the condensate, and can also enable part of wet hot air flowing along the air flow path to be in contact with the condensate in the condensing groove 121a, the condensate overflowing from the condensing groove 121a can form a water curtain in the falling process, and the wet hot air flowing along the air flow path can be in full contact with the water curtain when passing through the water curtain, that is, the condensate gathered in the condensing groove 121a and the water curtain formed in the falling process after the condensate overflows from the condensing groove 121a can jointly improve the contact area of the wet hot air and the condensate, so that the wet hot air can be in full heat exchange with the condensate, and the condensing effect can be improved.
In addition, since the wet hot air can be sufficiently contacted with the condensate and the water curtain gathered in the flow gathering groove 121a, the flock entrained in the wet hot air can be more easily mixed with the condensed water into the condensate, and thus, the effect of filtering and removing the flock can be improved.
It should be noted that, the condensing apparatus in the related art is generally vertically arranged, and the water inlet, the water outlet, the air inlet and the air outlet are all vertically arranged, wherein the air inlet and the water outlet are arranged at a low position, and the air outlet and the water inlet are arranged at a high position, that is, the condensate entering the condensing apparatus from the water inlet flows vertically downwards, the damp and hot airflow entering the condensing apparatus from the air inlet flows vertically upwards, and the damp and hot airflow passes through the condensate flowing vertically downwards in the process of flowing vertically upwards, so as to achieve the condensing effect. However, the condensing device needs a larger condensate fall and a larger airflow flowing distance, so the condensing device has a larger volume, more structural limitations and difficult guarantee of the condensing effect.
The condensate flow path of the condensing device extends downwards along the vertical direction, the airflow flow path extends along the transverse direction, meanwhile, the flow guide assembly with the flow collecting plate is arranged at the intersection of the condensate flow path and the airflow flow path, the flow collecting groove of the flow collecting plate can collect condensate, and the condensate is guided to overflow from at least one of two opposite sides of the flow collecting groove along the airflow flow direction to form a water curtain through which hot and humid airflow can pass. Because the air flow path of the condensing device extends along the transverse direction, the condensing device does not need a large condensate drop, and does not need a large air flow flowing distance in the vertical direction, namely, the condensing device is not influenced by the condensate drop and the air flow flowing distance, the structure is relatively compact, the condensing device is flexible and changeable, and can adapt to more functional structures, and the condensate gathered in the flow gathering groove and the water curtain formed in the falling process after the condensate overflows from the flow gathering groove can improve the contact area of the wet hot air flow and the condensate, so that the wet hot air flow can fully exchange heat with the condensate, thereby improving the condensing effect. That is to say, the condensing equipment of this application embodiment not only structure is compact relatively, and has better condensation effect.
For example, referring to fig. 2 and 3, the highest point of the air inlet 11a may be higher than the lowest point of the air outlet 11b, that is, the air inlet 11a has at least a partial region with a higher setting height than the air outlet 11b, and the air inlet 11a shown in fig. 2 and 3 has only a partial region with a higher setting height than the air outlet 11b, which is equivalent to a smaller height difference between the air inlet 11a and the air outlet 11b, which is beneficial to reducing the height dimension of the condensation pipe 11 and saving the installation space of the condensation pipe 11 in the height direction. It should be noted that, when the air inlet 11a is vertically arranged or obliquely arranged as shown in fig. 2 and 3, the air inlet 11a has distinct highest point and lowest point, and when the air inlet 11a is horizontally arranged (i.e. in the same way as the air outlet 11b shown in fig. 2 and 3), the air inlet 11a has only one set height, which is equal to the set height of the highest point of the air inlet 11 a. Similarly, when the outlet 11b is vertically or obliquely arranged, the outlet 11b has obvious highest point and lowest point, and when the outlet 11b is horizontally arranged as shown in fig. 2 and 3, the outlet 11b has only one set height, which is equal to the set height of the lowest point of the outlet 11 b.
In some embodiments, the highest point of the air inlet 11a may be set to a height equal to the lowest point of the air outlet 11b, or the highest point of the air inlet 11a may be set to a height lower than the lowest point of the air outlet 11 b.
The setting position of the water inlet 11c of this application embodiment can be adjusted as required, and more preferably, please refer to fig. 2 to 4, the water inlet 11c can be set up on the top wall of the condenser pipe 11, the top wall of the condenser pipe 11 in fig. 2 to 4 is provided with the inlet tube, the inlet of the inlet tube is the water inlet 11c, in some embodiments, the water inlet 11c that runs through the top wall can also be formed on the top wall.
The relative height between the water inlet 11c and the air outlet 11b can also be adjusted according to the requirement, for example, referring to fig. 2 to 4, the highest point of the water inlet 11c can be set higher than the lowest point of the air outlet 11b, that is, the water inlet 11c is set higher than the air outlet 11b in at least a partial region. It should be noted that the definition of the highest point of the water inlet 11c is the same as that of the highest point of the air inlet 11 a. The water inlet 11c and the air outlet 11b shown in fig. 2 to 4 are both horizontally disposed, and although the whole water inlet 11c is disposed at a height higher than that of the air outlet 11b, the height difference between the water inlet 11c and the air outlet 11b is relatively small, so that the height dimension of the condensation pipe 11 is also reduced, and the installation space of the condensation pipe 11 in the height direction is saved.
In some embodiments, the highest point of the water inlet 11c may be set to be equal to the lowest point of the air outlet 11b, or the highest point of the water inlet 11c may be set to be lower than the lowest point of the air outlet 11 b.
In one embodiment, referring to fig. 3 to 5, the condensation duct 11 may form an airflow channel 11e having an air inlet 11a and an air outlet 11b, that is, the airflow path is located in the airflow channel 11e, the water inlet 11c may be located at an upper side of the airflow channel 11e, the water outlet 11d may be located at a lower side of the airflow channel 11e, a height of the water outlet 11d relative to the water inlet 11c is higher than a height of the airflow channel 11e, and a height of the water outlet 11d is lower than the height of the airflow channel 11 e.
In one embodiment, referring to fig. 3, a partition 11f may be disposed in the condensation duct 11, the partition 11f divides the condensation duct 11 into an air flow channel 11e and a drainage channel 11g located at a lower side of the air flow channel 11e, wherein the drainage channel 11g has a drainage port 11d, that is, a part of a flow path of the condensate passes through the drainage channel 11 g. Part of the edge of the partition wall 11f in fig. 3 is spaced apart from the inner wall of the condensation duct 11 so that a water passing opening communicating the air flow path and the drainage channel 11g is formed at the space, and in some embodiments, the water passing opening may be formed directly on the partition wall 11 f. After passing through the airflow flow path, the condensate flows from the drain port into the drain passage 11g and is discharged from the drain port 11 d. The drain passage 11g may serve to collect the condensate so as to discharge the condensate from the drain port 11d in time.
In addition, referring to fig. 4 and 5, the flow guiding assembly 12 may be located downstream of the water gap in the air flow direction, which is equivalent to the damp heat air flow firstly passing through the water gap and then passing through the condensate. The partial area of the partition wall 11f facing the side of the flow guiding assembly 12 may form a flow guiding surface 11h, the flow guiding surface 11h guides the flow path of the condensate to extend toward the water passing opening, the flow guiding surface 11h in fig. 4 and 5 is a curved surface, in some embodiments, the flow guiding surface 11h may also be an inclined plane, the condensate flowing through the flow guiding assembly 12 after falling on the flow guiding surface 11h may flow toward the water passing opening along the flow guiding surface 11h, which is equivalent to the flow direction of the condensate flowing along the flow guiding surface 11h being opposite to the flow direction of the air flow, thereby preventing the condensate from flowing toward the air outlet 11b along with the condensed low-temperature drying air flow as much as possible.
In one embodiment, referring to fig. 2 and 3, the airflow channel 11e may also have a first extension 11e1 and a second extension 11e 2; the second extension section 11e2 is communicated with the first extension section 11e1 and extends to one side of the first extension section 11e1, that is, a certain included angle is formed between the second extension section 11e2 and the first extension section 11e1, an air inlet 11a is formed at one end of the first extension section 11e1 far away from the second extension section 11e2, an air outlet 11b is formed at one end of the second extension section 11e2 far away from the first extension section 11e1, and the condensate flow path passes through the first extension section 11e 1.
Specifically, for convenience of description, it may be considered that the first extension 11e1 extends along the length direction of the condensation duct 11, the second extension 11e2 extends along the width direction of the condensation duct 11, and the provision of the second extension 11e2 may save the length of the condensation duct 11, so as to make the overall structure of the condensation device 10 more compact. In addition, a small amount of fine droplets formed by condensate may be entrained in the low-temperature drying airflow formed after condensation, and therefore, by providing the first extension 11e1 and the second extension 11e2, a corner may be formed at the connection between the first extension 11e1 and the second extension 11e2, and when the low-temperature drying airflow passes through the connection between the first extension 11e1 and the second extension 11e2, the fine droplets entrained in the low-temperature drying airflow may be thrown onto the side wall of the airflow channel 11e by the centrifugal force, and thus, the condensate may be prevented from flowing to the air outlet 11b along with the airflow as much as possible.
The converging chute 121a can be formed in various manners, for example, referring to fig. 4, the top end surface of the converging plate 121 defines the converging chute 121a, that is, the converging chute 121a can be formed by using a non-planar top end surface, for example, the converging plate 121 can be bent to form the converging chute 121a on the top end surface. Specifically, the top end surface of the current collecting plate 121 shown in fig. 4 is a curved surface that is curved toward the bottom end surface close to the current collecting plate 121, and in some embodiments, the top end surface may also include at least two inclined surfaces, which may be both inclined planes, or one part of the inclined planes may be an inclined plane and the other part may be an inclined curved surface, and the inclined planes are connected in sequence, and may also define a current collecting groove 121 a.
In some embodiments, a partial area of the top of the flow collecting plate 121 may be recessed to form the flow collecting groove 121 a.
The relative position of the current collecting plate 121 and the water inlet 11c can be determined as required, as long as the condensate flowing into the condensation pipe 11 from the water inlet 11c can flow into the current collecting groove 121a, for example, referring to fig. 4, the relative position of the current collecting plate 121 and the water inlet 11c can be: the axial center line of the water inlet 11c passes through the current collecting plate 121, i.e., the arrangement of the first current collecting plate 121b, the second current collecting plate 121c and the third current collecting plate 121d in fig. 4. In some embodiments, the relative position of the flow collecting plate 121 and the water inlet 11c may also be: the current collecting plate 121 is located on one of opposite sides of the axial center line of the inlet port 11c in the flow direction of the air current.
As shown in fig. 3 to 7, for example, each of the flow collecting plates 121 may be arranged in a vertically layered manner, that is, each of the flow collecting plates 121 may be arranged in a vertically sequential manner at intervals to form a multi-layer structure.
Further, referring to fig. 3 to 7, for the flow focusing plates 121 of the multilayer structure, the relative positions of at least some of the vertically adjacent flow focusing plates 121 may satisfy: in the condensate flow direction, the flow collecting grooves 121a of the downstream flow collecting plates 121 can receive at least part of the condensate overflowing from the flow collecting grooves 121a of the upstream flow collecting plates 121, that is, at least two vertically adjacent flow collecting plates 121 are located opposite to each other such that at least part of the condensate overflowing from the flow collecting groove 121a of one flow collecting plate 121 can flow into the flow collecting groove 121a of the other flow collecting plate 121 located below the flow collecting plate 121 and adjacent to the flow collecting groove 121 a.
Specifically, taking fig. 4 and 5 as an example, three current collecting plates 121 are shown in fig. 4 and 5, and the three current collecting plates 121 are arranged vertically from top to bottom, and for convenience of description, the three current collecting plates 121 may be referred to as a first current collecting plate 121b, a second current collecting plate 121c, and a third current collecting plate 121d, respectively. In fig. 4 and 5, the first current collecting plate 121b and the second current collecting plate 121c are vertically adjacent to each other, the first current collecting plate 121b is located upstream of the second current collecting plate 121c in the flowing direction of the condensate, and the horizontal projection of the first current collecting plate 121b is located in the horizontal projection area of the current collecting groove 121a of the second current collecting plate 121c, and it should be noted that the horizontal projection refers to the projection on the horizontal plane perpendicular to the vertical direction. That is, the condensate overflowing from the flow collecting grooves 121a of the first flow collecting plate 121b can flow into the flow collecting grooves 121a of the second flow collecting plate 121c from the opposite sides of the flow collecting grooves 121a of the first flow collecting plate 121b in the air flow direction, respectively, which is equivalent to that the condensate overflowing from the flow collecting grooves 121a of the first flow collecting plate 121b all flows into the flow collecting grooves 121a of the second flow collecting plate 121c, similarly, the second flow collecting plate 121c and the third flow collecting plate 121d are vertically adjacent to each other, the second flow collecting plate 121c is located upstream of the third flow collecting plate 121d in the condensate flow direction, the horizontal projection of the second flow collecting plate 121c is located in the horizontal projection area of the third flow collecting plate 121d, and the condensate overflowing from the flow collecting grooves 121a of the second flow collecting plate 121c all flows into the flow collecting grooves 121a of the third flow collecting plate 121 d.
It should be noted that only a portion of the condensate overflowing from the flow collecting groove 121a of one flow collecting plate 121 may flow into the flow collecting groove 121a of another flow collecting plate 121 located below and adjacent to the flow collecting plate 121, for example, in another embodiment, referring to fig. 6, for convenience of description, two opposite sides of the condensing device 10 in the airflow direction may be referred to as a first side and a second side, respectively, in fig. 6, a side of the condensing device 10 located upstream in the airflow direction is referred to as a first side, a side of the condensing device 10 located downstream in the airflow direction is referred to as a second side, in some embodiments, a side of the condensing device 10 located upstream in the airflow direction is referred to as a second side, a side of the condensing device 10 located downstream in the airflow direction is referred to as a first side, and positions corresponding to the first side and the second side may be interchanged. In fig. 6, the horizontal projection of the first side of the first current collecting plate 121b is located in the horizontal projection area of the current collecting groove 121a of the second current collecting plate 121c, the horizontal projection of the second side of the first current collecting plate 121b and the horizontal projection of the second side of the second current collecting plate 121c are both located in the horizontal projection area of the current collecting groove 121a of the third current collecting plate 121d, and after the condensate overflows from the current collecting groove 121a of the first current collecting plate 121b, the condensate flowing down from the first side of the first current collecting plate 121b flows into the current collecting groove 121a of the second current collecting plate 121c, the condensate flowing down from the second side of the first current collecting plate 121b flows into the current collecting groove 121a of the third current collecting plate 121d, and after the condensate flowing into the current collecting groove 121a of the second current collecting plate 121c overflows from the current collecting groove 121a of the second current collecting plate 121c, the condensate flowing down from the second side of the second current collecting plate 121c also flows into the current collecting groove 121a of the current collecting plate 121d, and the condensate flowing down from the first side of the second current collecting plate 121c does not flow into the current collecting groove 121a of the third current collecting plate 121 d.
In the diversion assembly 12 shown in fig. 4 and 6, the flow collecting grooves 121a of the downstream flow collecting plates 121 can each receive at least part of the condensate overflowing from the flow collecting grooves 121a of the adjacent and upstream flow collecting plates 121, and in another embodiment, referring to fig. 7, the relative positions of the first flow collecting plate 121b, the second flow collecting plate 121c, and the third flow collecting plate 121d can also be: the horizontal projection of the first side of the first current collecting plate 121b is located in the horizontal projection area of the current collecting groove 121a of the second current collecting plate 121c, the horizontal projection of the second side of the first current collecting plate 121b is located in the horizontal projection area of the current collecting groove 121a of the third current collecting plate 121d, the horizontal projection of the second side of the second current collecting plate 121c is offset from the horizontal projection area of the first side of the third current collecting plate 121d, that is, after the condensate overflowing from the current collecting groove 121a of the first current collecting plate 121b flows down from the first side of the first current collecting plate 121b, the condensate can flow into the current collecting groove 121a of the second current collecting plate 121c, the condensate flowing down from the second side of the first current collecting plate 121b can flow into the current collecting groove 121a of the third current collecting plate 121d, but after the condensate overflowing from the second side 121a of the second current collecting plate 121c does not flow into the current collecting groove 121a of the third current collecting plate 121d, but continues to flow downwards while avoiding the third current collecting plate 121d, that is, the current collecting groove 121a of the second current collecting plate 121c can contain the partial condensate overflowing from the current collecting groove 121a of the first current collecting plate 121b located adjacent and upstream, but the current collecting groove 121a of the third current collecting plate 121d does not contain the partial condensate overflowing from the current collecting groove 121a of the second current collecting plate 121c located adjacent and upstream, and in other words, the relative positions of only some vertically adjacent current collecting plates 121 in the plurality of current collecting plates 121 satisfy: in the condensate flow direction, the flow collecting groove 121a of the downstream flow collecting plate 121 may receive at least a portion of the condensate overflowing from the flow collecting groove 121a of the upstream flow collecting plate 121.
The flow collecting groove 121a of the flow collecting plate 121 located at the downstream in the flowing direction of the condensate receives at least part of the condensate overflowing from the flow collecting groove 121a of the adjacent and upstream flow collecting plate 121, so that not only can a water curtain be formed between the two adjacent flow collecting plates 121, but also the flow velocity of the condensate can be reduced, and therefore, the condensation, filtration and chip removal effects can be further improved. Especially, when the flow collecting grooves 121a of at least some of the flow collecting plates 121 of the plurality of flow collecting plates 121 can also guide the condensate to flow to the flow collecting grooves 121a along opposite sides of the airflow flowing direction, the condensing, filtering and debris removing effects of the condensing device 10 can be greatly improved.
In addition, referring to fig. 7, although the collecting groove 121a of the third flow plate 121d in fig. 7 does not receive the condensate overflowing from the collecting groove 121a of the second flow plate 121c located adjacent to and upstream of the collecting groove 121a, the condensate overflowing from the collecting groove 121a of the second flow plate 121c also forms a single water curtain after flowing down from the second side of the second flow plate 121c, that is, the flow guide assembly 12 shown in fig. 7 increases the number of water curtains below the third flow plate 121d compared to the flow guide assembly 12 shown in fig. 4, thereby improving the condensation and filtering debris removal effects of the condensing device 10.
In another embodiment, referring to fig. 8, the flow guiding assembly 12 may also be a plurality of flow collecting plates 121, some of the flow collecting plates 121 are vertically layered, and some of the flow collecting plates 121 are laterally spaced apart, that is, the flow guiding assembly 12 shown in fig. 8 also has a multilayer structure, but compared with the flow guiding assembly 12 shown in fig. 4 to 7, at least one of the layers of the flow guiding assembly 12 shown in fig. 8 may have at least two flow collecting plates 121, and at least two flow collecting plates 121 of the same layer are laterally spaced apart.

In an embodiment, referring to fig. 3 to 8, the diversion assembly 12 may further include a diversion plate 122, similar to the flow collecting plate 121, the diversion plate 122 may also guide the condensate to flow to at least one of two opposite sides of the diversion plate 122 along the flow direction of the air flow, but the diversion plate 122 does not include a flow collecting groove 121a, that is, the diversion plate 122 mainly performs the diversion function, and the flow collecting effect is relatively poor.
In the diversion assembly 12 shown in fig. 3 to 8, only one diversion plate 122 is disposed downstream of the plurality of flow collecting plates 121 in the flow direction of the condensate, and the diversion plate 122 is disposed horizontally, it can be understood that the disposition position, number, disposition angle, and the like of the diversion plate 122 can be adjusted as required, for example, the diversion plate 122 can be disposed upstream of the plurality of flow collecting plates 121 in the flow direction of the condensate, or between two flow collecting plates 121, the number of the diversion plates 122 can be plural, and the diversion plate 122 can also be disposed obliquely.
When the condensate on the flow guide plate 122 flows to at least one of the two opposite sides of the flow guide plate 122 along the air flow direction, the condensate can also contact the hot and humid air flow, and the condensate flowing down from the flow guide plate 122 can also form a water curtain, so that the flow guide plate 122 can also have better condensation, filtering and scrap removing effects.
It is understood that in some embodiments, only the flow focusing plate 121 may be provided, and the flow guide plate 122 may not be provided.
In one embodiment, the barrel assembly 20 includes an inner barrel and an outer barrel, the inner barrel is rotatably disposed in the outer barrel, and the condensing device 10 is connected to the outer barrel.

When the laundry treating apparatus is a pulsator type laundry treating apparatus, the condensing device 10 may be disposed at any one side of the drum assembly 20 in a circumferential direction.
Wherein, the inner cylinder can be a non-hole inner cylinder or a hole inner cylinder. When the inner cylinder is a porous inner cylinder, water is contained by the outer cylinder. When the inner barrel is a non-hole type inner barrel, water can be contained in the inner barrel, namely, the inner barrel can contain water and clothes, the water in the inner barrel cannot enter the outer barrel in the washing process, and the water can be drained through the outer barrel in the drainage process.
